Nested dissection by METIS/ParMETIS (NODEND)The parenthetical string is the parameter value for ORDER_METHOD parameter; the parameter is set through a call to Zoltan_Set_Param.
Parameters: | |
ORDER_METHOD | The order algorithm used by Zoltan is specified by this parameter.
Valid values are
"NODEND" (for nodal nested dissection by ParMETIS or METIS), |
ORDER_TYPE | "LOCAL" or "GLOBAL". If LOCAL is selected, then each processor constructs a local (sub-)graph. All inter-processor edges are simply ignored. The ordering arrays returned, rank and iperm, are local permutation vectors in this case. |
ORDER_START_INDEX | The start index for the permutation vectors rank and iperm. Valid values are 0 and 1. |
REORDER | If this value is set to TRUE (non-zero), Zoltan assumes that the lists of local and global ids are given as input to Zoltan_Order. Otherwise, the id lists will be populated by Zoltan_Order. The permutation of the ids will be the one produced by calling the query functions. |
Default Values: | |
ORDER_METHOD = NODEND | |
ORDER_TYPE = GLOBAL | |
ORDER_START_INDEX = 0 | |
REORDER = FALSE |
